Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support pipe technology, and more specifically, it relates to a multi-hole hydraulic indexing and positioning table for photovoltaic support pipes. Background Technology

[0002] Photovoltaic support pipes are an important component of photovoltaic support systems, mainly used to support photovoltaic modules so that they can receive solar energy at a suitable angle. They are usually tubular structures and require multiple holes of different specifications and positions to be machined in the pipe walls and other locations to meet the needs of connection and installation with other components. A hydraulic indexing and positioning table is a device that uses hydraulic power to achieve workpiece indexing and positioning, thereby assisting in the completion of multi-hole machining operations. In the multi-hole machining process of photovoltaic support pipes, positioning tables are often used to ensure the accuracy and efficiency of hole machining.

[0003] However, existing indexing and positioning mechanisms mostly use a single hydraulically driven chuck to clamp the pipe fittings and perform indexing rotation. However, in actual use, because the clamping surface of the hydraulically driven chuck is relatively simple and lacks limiting assistance for different directions of the pipe fittings, when the pipe fittings are machined with multiple holes, especially when the machining positions are relatively dispersed or require large machining forces, the pipe fittings are prone to slight offsets or wobbling on the chuck. This will cause deviations between the machined holes and the designed positions, affecting the assembly accuracy of the photovoltaic bracket pipe fittings, and may reduce the overall structural stability and service life of the photovoltaic bracket, thus failing to meet the requirements of the photovoltaic bracket system for high-precision components. Utility Model Content

[0004] (a) Technical problems to be solved In view of the above situation and to overcome the defects of the prior art, this utility model provides a multi-hole hydraulic indexing and positioning table for photovoltaic support pipes, which aims to solve the problems in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this application provides the following technical solution: a multi-hole hydraulic indexing and positioning table for photovoltaic bracket pipe fittings, comprising a base, two symmetrically positioned fixed platforms fixedly connected to the upper surface of the base, a first ball bearing fixedly connected to the inner wall of the middle of each fixed platform, a rotating shaft fixedly connected to the inner ring of each first ball bearing, a first clamping plate fixedly connected to the end of each of the two rotating shafts that are close to each other, a first electric push rod fixedly connected to the side of each of the two first clamping plates that are close to each other, a second clamping plate fixedly connected to the telescopic end of each first electric push rod, a first annular telescopic sleeve fixedly connected to the side of each of the first and second clamping plates that are close to each other, multiple annularly arranged adjustment grooves provided on the side of each first clamping plate away from the fixed platform and the side of each second clamping plate away from the fixed platform, two clamping seats provided inside each adjustment groove, an adjustment seat slidably connected to the end of the inner wall of each adjustment groove opposite to one of the clamping seats, two symmetrically fixed plates fixedly connected to the outer surface of each clamping seat, and each pair of fixed plates... The inner walls of the plates are all connected by a common threaded fixing bolt. Two movable slots are formed on the upper surface of the middle part of the base. A movable plate is slidably connected inside each movable slot. A movable seat is fixedly connected to the upper surfaces of the two movable plates. An assembly plate is fixedly connected to the rear middle part of the upper surface of the base. Two second electric push rods are fixedly connected to the front of the assembly plate and the back of the movable seat. Two third electric push rods are fixedly connected to the inner bottom wall of the movable seat. An adjustment frame is fixedly connected to the telescopic ends of the two third electric push rods. The adjustment frame has two sides... Two second ball bearings are fixedly connected to the inner wall. The inner rings of the two second ball bearings are fixedly connected to an adjusting shaft. The left end of the adjusting shaft extends to the left side of the adjusting frame. A limiting plate is fixedly connected to the left end of the adjusting shaft. A ring-shaped limiting groove is provided on the left side of the adjusting frame. Four limiting rods are engaged inside the four limiting grooves. An auxiliary plate is fixedly connected to the left end of the four limiting rods. A positioning seat is fixedly connected to the outer surface of the adjusting shaft. A stepper motor is fixedly connected to the right side of one of the fixed platforms by bolts.

[0006] The present invention is further configured such that one of the clamping seats in each adjustment groove is fixedly connected to one end of the inner wall of the adjustment groove, and the side of each adjustment seat away from the fixed platform is fixedly connected to the outer surface of the other clamping seat, and each pair of clamping seats is symmetrically distributed.

[0007] The present invention is further configured such that the left end of each of the limiting rods extends through to the left side of the limiting rotating plate, the right side of the auxiliary plate contacts the left side of the adjusting frame, the upper surface of the positioning seat is fixedly connected to the first anti-slip plate, and the output end of the stepper motor is fixedly connected to the right end of one of the rotating shafts.

[0008] The present invention is further configured such that annular grooves are provided on the sides of the two fixed platforms that are close to each other, and multiple sliding rods are slidably connected inside each annular groove. One end of each sliding rod inside the annular groove is spherical. Annular fixing frames are fixedly connected on the sides of the two first clamping discs that are far from each other, and the side of each annular fixing frame that is close to the fixed platform is fixedly connected to the right end of the sliding rod.

[0009] The present invention is further configured such that each of the clamping seats has a second anti-slip plate inside, and the outer surface of each second anti-slip plate is fixedly connected to the inner wall of the clamping seat.

[0010] The present invention is further configured such that four second telescopic sleeves are fixedly connected to the inner bottom wall of the movable seat, and the top end of each second telescopic sleeve is fixedly connected to the bottom surface of the adjustment frame, and the bottom surface of the adjustment frame is in contact with the upper surface of the movable seat in the initial state.

[0011] (III) Beneficial Effects Compared with the prior art, the beneficial effects of this utility model are: 1. The first ball bearing and the rotating shaft are supported by two fixed platforms respectively, so that the two first clamping plates form a symmetrical clamping structure. With the adjustment grooves distributed in the ring on the first clamping plate and the clamping seats in the grooves, the two ends of the photovoltaic bracket tube of a certain length or a long length can be initially limited. At the same time, the first electric push rod drives the second clamping plate to adjust the distance between the second clamping plate and the first clamping plate along the axial displacement, which can adapt to tubes of different lengths and further clamp them. The first telescopic sleeve extends and retracts synchronously with the movement of the second clamping plate, which enhances the stability of the second clamping plate during displacement, avoids the problem of unstable clamping of long tubes or tubes of different lengths by a single clamping structure, prevents the tube from shifting during processing and causing hole position deviation, and ensures the assembly accuracy of the photovoltaic bracket tube. 2. After adjustment by the second and third electric push rods, the adjusting seat can fit tightly against the bottom of the pipe to form a reliable support. In conjunction with the second anti-slip plate inside the clamping seat, the friction between the clamping seat and the pipe is increased, further improving the clamping firmness. At the same time, when the stepper motor drives the rotating shaft to rotate the pipe at the indexing position, the annular fixing frame and the sliding rod slide in the annular groove to assist the first clamping plate to rotate stably, reduce radial runout, and prevent long pipes or pipes of different lengths from shaking during indexing due to the lack of effective bottom limit. This prevents a decrease in hole machining accuracy, avoids affecting the overall structural stability of the photovoltaic bracket, reduces component wear, and extends the service life of the equipment.

[0017] Please see Figures 1-6The system includes a base 1, on the upper surface of which are fixedly connected two symmetrical fixed platforms 2. A first ball bearing 16 is fixedly connected to the inner wall of the middle portion of each fixed platform 2. A rotating shaft 17 is fixedly connected to the inner ring of each first ball bearing 16. A first clamping plate 3 is fixedly connected to one end of each rotating shaft 17 that is close to the other. A first electric push rod 34 is fixedly connected to one side of each first clamping plate 3 that is close to the other. A second clamping plate 4 is fixedly connected to the telescopic end of each first electric push rod 34. A first clamping plate 3 is fixedly connected to one side of each first clamping plate 3 and second clamping plate 4 that is close to the other. A first telescopic sleeve 5 in an annular shape is fixedly connected to the base 1. Multiple annularly arranged adjusting grooves 22 are provided on the side of each first clamping plate 3 away from the fixed platform 2 and on the side of each second clamping plate 4 away from the fixed platform 2. Two clamping seats 10 are provided inside each adjusting groove 22. An adjusting seat 23 is slidably connected to the end of the inner wall of each adjusting groove 22 opposite to one of the clamping seats 10. Two symmetrically arranged fixing plates 25 are fixedly connected to the outer surface of each clamping seat 10. A fixing bolt 26 is threadedly connected to the inner wall of each pair of fixing plates 25. Two movable slots 15 are formed on the upper surface of the base 1. A movable plate 13 is slidably connected inside each movable slot 15. A movable seat 14 is fixedly connected to the upper surface of the two movable plates 13. An assembly plate 6 is fixedly connected to the rear side of the middle part of the upper surface of the base 1. Two second electric push rods 7 are fixedly connected to the front of the assembly plate 6 and the back of the movable seat 14. Two third electric push rods 19 are fixedly connected to the inner bottom wall of the movable seat 14. An adjustment frame 12 is fixedly connected to the telescopic ends of the two third electric push rods 19. Two second ball bearings are fixedly connected to the inner walls on both sides of the adjustment frame 12. The inner rings of the two second ball bearings 33 are fixedly connected to the adjusting shaft 31. The left end of the adjusting shaft 31 extends to the left side of the adjusting frame 12. The left end of the adjusting shaft 31 is fixedly connected to the limiting plate 28. The left side of the adjusting frame 12 is provided with a ring-shaped limiting groove 32. The four limiting grooves 32 are engaged with four limiting rods 30. The left ends of the four limiting rods 30 are fixedly connected to the auxiliary plate 29. The outer surface of the adjusting shaft 31 is fixedly connected to the positioning seat 11. The right side of one of the fixed platforms 2 is fixedly connected to the stepper motor 21 by bolts.

[0018] Specifically, the rotating shaft 17, fixed by the inner ring of the first ball bearing 16, can drive the first clamping plate 3 to rotate flexibly. The first electric push rod 34 on the first clamping plate 3 can drive the second clamping plate 4 to move axially, adjusting the distance between the second clamping plate 3 and the first clamping plate 4 to adapt to photovoltaic bracket fittings of different lengths. The first telescopic sleeve 5 moves synchronously with the second clamping plate 4, enhancing the displacement stability of the second clamping plate 4. The adjustment grooves 22 on the first clamping plate 3 and the second clamping plate 4 provide installation and sliding space for the clamping seat 10 and the adjustment seat 23. The sliding adjustment seat 23 can adjust the distance between the two clamping seats 10 to adapt to fittings of different diameters. The fixing plate 25 and the fixing bolt 26 cooperate to lock the position of the clamping seat 10. The displacement on the base 1 The moving groove 15 allows the moving plate 13 to slide, driving the moving seat 14 to adjust its position. The second electric push rod 7 on the assembly plate 6 can push the moving seat 14 to move precisely. The third electric push rod 19 inside the moving seat 14 can drive the adjusting frame 12 to rise and fall. The second ball bearing 33 inside the adjusting frame 12 makes the adjusting shaft 31 rotate stably. The adjusting shaft 31 drives the positioning seat 11 to adjust its angle. The limiting rotating plate 28, the limiting groove 32, the limiting rod 30 and the auxiliary plate 29 can lock the position of the adjusting shaft 31. The stepper motor 21 can drive the rotating shaft 17 to drive the pipe to rotate indexing, realizing stable clamping and precise indexing positioning of pipes of different specifications, solving the problem of pipe offset and shaking caused by the existing single clamping structure, and ensuring the accuracy of hole processing.

[0019] Please see Figures 1-6 In each adjustment groove 22, one of the clamping seats 10 is fixedly connected to one end of the inner wall of the adjustment groove 22, and the side of each adjustment seat 23 away from the fixed platform 2 is fixedly connected to the outer surface of the other clamping seat 10. Each pair of clamping seats 10 are symmetrically distributed.

[0020] Specifically, one clamping seat 10 is fixed to the groove wall in the adjustment groove 22, and the other clamping seat 10 is connected to the adjustment seat 23. When the adjustment seat 23 slides in the adjustment groove 22, it can drive the connected clamping seat 10 to move, so that the distance between the two symmetrically distributed clamping seats 10 is adapted to the diameter of the pipe fitting. This ensures that the clamping seats 10 can apply force evenly from both sides of the pipe fitting, avoiding the problem that the clamping seats 10 cannot be adapted to pipe fittings of different diameters due to their fixed positions, or that the pipe fittings will shift due to uneven force. This further improves the clamping adaptability and stability of pipe fittings of different specifications.

[0021] Please see Figures 1-6 The left end of each limiting rod 30 extends to the left side of the limiting rotating plate 28. The right side of the auxiliary plate 29 contacts the left side of the adjusting frame 12. The upper surface of the positioning seat 11 is fixedly connected to the first anti-slip plate 27. The output end of the stepper motor 21 is fixedly connected to the right end of one of the rotating shafts 17.

[0022] Specifically, the limiting rod 30 passes through the limiting rotating plate 28 and is inserted into the limiting groove 32. The auxiliary plate 29 contacts the adjusting frame 12 to enhance the stability of the limiting rod 30 and lock the position of the adjusting shaft 31 to prevent the adjusting shaft 31 from accidentally rotating the positioning seat 11. The first anti-slip plate 27 on the positioning seat 11 increases the friction with the bottom of the pipe to prevent the pipe from sliding on the positioning seat 11. The output end of the stepper motor 21 is connected to the rotating shaft 17, which can drive the rotating shaft 17 to drive the first clamping plate 3 and the pipe to rotate precisely at the indexing position, solving the problems of easy displacement of the pipe and easy loosening of the positioning seat 11 during the indexing rotation, and ensuring the indexing and positioning accuracy.

[0023] Please see Figures 1-6 Annular grooves 9 are provided on the sides of the two fixed platforms 2 that are close to each other. Multiple sliding rods 8 are slidably connected inside each annular groove 9. One end of each sliding rod 8 inside the annular groove 9 is spherical. Annular fixing frames 18 are fixedly connected on the sides of the two first clamping plates 3 that are far apart from each other. The side of each annular fixing frame 18 that is close to the fixed platform 2 is fixedly connected to the right end of the sliding rod 8.

[0024] Specifically, the annular groove 9 on the fixed platform 2 provides a sliding groove for the sliding rod 8 to slide. The spherical end of the sliding rod 8 reduces friction with the annular groove 9, making the sliding smoother. The other end of the sliding rod 8 is connected to the annular fixing frame 18, which is fixed on the first clamping plate 3. When the first clamping plate 3 rotates with the rotating shaft 17, the annular fixing frame 18 drives the sliding rod 8 to slide synchronously in the annular groove 9, providing circumferential support for the first clamping plate 3. This prevents the first clamping plate 3 from radially jumping during rotation due to being supported only by the rotating shaft 17, thus solving the problem of unstable rotation of the first clamping plate 3 affecting the indexing accuracy of the pipe fitting and improving the overall rotational stability.

[0025] Please see Figures 1-6 Each clamping seat 10 is provided with a second anti-slip plate 24 inside. The outer surface of each second anti-slip plate 24 is fixedly connected to the inner wall of the clamping seat 10. Four second telescopic sleeves 20 are fixedly connected to the inner bottom wall of the moving seat 14. The top of each second telescopic sleeve 20 is fixedly connected to the bottom surface of the adjusting frame 12. The bottom surface of the adjusting frame 12 is in contact with the upper surface of the moving seat 14 in the initial state.

[0026] Specifically, the second anti-slip plate 24 inside the clamping seat 10 contacts the surface of the pipe, increasing the friction between the clamping seat 10 and the pipe, preventing the pipe from sliding inside the clamping seat 10. The second telescopic sleeve 20 inside the moving seat 14 connects the moving seat 14 and the adjusting frame 12. When the third electric push rod 19 drives the adjusting frame 12 to rise and fall, the second telescopic sleeve 20 extends and retracts synchronously, providing guidance and support for the adjusting frame 12, avoiding tilting and deviation when the adjusting frame 12 rises and falls, solving the problem that the pipe is easy to slide from the clamping seat 10 and the adjusting frame 12 is unstable in rising and falling, and further ensuring the clamping and adjustment accuracy.

[0027] Working principle: When machining multi-hole photovoltaic bracket pipes, the pipe is first placed between two first clamping discs 3. The rotating shaft 17 of the inner ring of the first ball bearing 16 can drive the first clamping disc 3 to rotate flexibly. The first electric push rod 34 on the first clamping disc 3 is activated to drive the second clamping disc 4 to move axially. The distance between the second clamping disc 4 and the first clamping disc 3 is adjusted to match the length of the pipe. The first telescopic sleeve 5 moves synchronously with the second clamping disc 4 to enhance the displacement stability of the second clamping disc 4. According to the diameter of the pipe, the adjusting seat 23 in the adjusting groove 22 is pushed to drive the clamping seat 10 connected to it to slide, and the distance between the two clamping seats 10 is adjusted. Then, the position of the clamping seat 10 is locked by the fixing plate 25 and the fixing bolt 26. The second anti-slip plate 24 in the clamping seat 10 increases the friction with the pipe to prevent the pipe from sliding. Then, the second electric push rod 7 on the assembly plate 6 is activated to push the moving seat 14 to slide along the moving plate 13 in the moving groove 15 to the bottom of the pipe. The first electric push rod 24 in the moving seat 14 is activated. Three electric push rods 19 drive the adjustment frame 12 to rise and fall. The second telescopic sleeve 20 provides guide support for the adjustment frame 12, so that the positioning seat 11 fits against the bottom of the pipe. The angle of the positioning seat 11 is adjusted by rotating the adjustment shaft 31. The second ball bearing 33 in the adjustment frame 12 ensures the stable rotation of the adjustment shaft 31. The first anti-slip plate 27 on the positioning seat 11 further prevents the pipe from sliding. Then, the limiting rod 30 is inserted into the limiting groove 32 through the limiting rotating plate 28. The auxiliary plate 29 enhances stability to lock the adjustment shaft 31, and the pipe can be processed. When the next pipe needs to be processed, the stepper motor 21 is started to drive the rotating shaft 17 to drive the pipe to rotate index. At this time, the annular fixing frame 18 on the first clamping plate 3 drives the sliding rod 8 to slide in the annular sliding groove 9 of the fixed table 2, reducing the radial runout of the first clamping plate 3, realizing stable clamping and precise indexing positioning of pipes of different specifications, solving the problem of pipe offset and shaking caused by the existing single clamping structure, and ensuring the accuracy of hole processing.

For all the fixed connections mentioned above, welding is preferred.
